Environmental impact of modern agriculture
 
07:48
Environmental impact of modern agriculture • The environmental impact of modern agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. • The environmental impact depends on the production practices of the system used by farmers. • The connection between emissions into the environment and the farming system is indirect, as it also depends on other climate variables such as rainfall and temperature. • There are two types of indicators of environmental impact: "Means-based", which is based on the farmer's production methods. For ex: the quality of groundwater, that is effected by the amount of nitrogen applied to the soil, and "effect-based", which is the impact that farming methods have on the farming system or on emissions to the environment. For ex: An indicator reflecting the loss of nitrate to groundwater. Issues related to Agriculture Climate change • Assessment of the effects of global climate changes on agriculture might help to properly anticipate and adapt farming to maximize agricultural production. • Agriculture has been shown to produce significant effects on climate change, primarily through the production and release of greenhouse gases such as carbon dioxide, methane, and nitrous oxide that affect air, water, and soil quality, as well as biodiversity. • Agriculture also alters the Earth's land cover, which can change its ability to absorb or reflect heat and light, thus contributing to radiative forcing. Deforestation • Deforestation is clearing a wide area of trees. One of the causes of deforestation is to clear land for pasture or crops. • Trees act as a carbon sink: that is, they absorb carbon dioxide, an unwanted greenhouse gas, out of the atmosphere. • Removing trees releases carbon dioxide into the atmosphere and leaves behind fewer trees to absorb the increasing amount of carbon dioxide. • It worsens climate change and causes extreme fluctuations in temperature. Genetic engineering • Genetically engineered crops are herbicide-tolerant, and their overuse has created herbicide resistant "super weeds", which may ultimately increase the use of herbicides. • Seed contamination is another problem of genetic engineering; it can occur from wind or bee pollination that is blown from genetically-engineered crops to normal crops. Irrigation • Among some of these problems is the depletion of underground aquifers through over-drafting. • Soil can be over-irrigated because of poor water distribution and poor management of waste water, chemicals, leads to water pollution. • Over-irrigation can cause deep drainage from rising water tables that can lead to problems of irrigation salinity requiring water table control by some form of subsurface land drainage. Pollutants • A wide range of agricultural chemicals are used in farming. some of them become pollutants through use, misuse, or ignorance. • Pesticides can leach through the soil and enter the groundwater, as well as linger in food products and result in death in humans. • The erosion of topsoil, which contains chemicals such as herbicides and pesticides, can be carried away from farms to other places. • Additional and specific problems that may arise with the release of pollutants from agriculture are Pesticide drift, soil contamination, air pollution spray drift, Pesticides, especially those based on organochloride, Pesticide residue in foods, Pesticide toxicity to bees, Bioremediation. Soil degradation • Soil degradation is the decline in soil quality that can be a result of many factors, especially from agriculture. • Soils hold the majority of the world's biodiversity, and healthy soils are essential for food production and an adequate water supply. • Common attributes of soil degradation can be Soil erosion, salting, waterlogging, pesticide contamination, decline in soil structure quality, loss of fertility, changes in soil acidity, alkalinity, and salinity. Waste • Plasticulture is the use of plastic mulch in agriculture. Farmers use plastic sheets as mulch to cover 50-70% of the soil and allows them to use drip irrigation systems to have better control over soil nutrients and moisture. • Rain is not required in this system, and farms that use Plasticulture are built to encourage the fastest runoff of rain. • The incineration and recycling options are complicated by the variety of the types of plastics that are used and by the geographic dispersal of the plastics. • While there has been minor success with this, there is also the problem of how long the plastic takes to degrade, as many biodegradable products take a long time to break down.

RUSSIA: ENVIRONMENT COMING UNDER INCREASING PRESSURE
 
03:19
Russian/Nat As Russia suffers a crippling financial crisis, the environment is coming under increasing pressure. From Moscow to Siberia to the Far East, "green" concerns are falling by the wayside as struggling industries and individuals focus all of their energies on just getting by. APTN takes a look at two industrial regions in Russia suffering the environmental consequences of the economic meltdown. This mining outpost is the world's largest city north of the Arctic Circle - freezing winds send snow squalls and factory smoke drifting across the endless polar tundra. More than 200-thousand Russians live in this forsaken land - the majority working in Norilsk's smelters and mines. The pollution pouring from Norilsk's unfiltered 20-plus smokestacks has poisoned the trees dead for a radius extending 150 kilometres from the town and its factories. Private environmental groups estimate that the average Norilskian takes in some 40 times more pollution than a resident of Moscow - a European capital itself more polluted then any of its neighbours. Norilsk was originally built by Soviet dictator Joseph Stalin as a prison camp. Today, it remains cut off from the rest of Russia - unreachable by road and impossible to escape for the majority of impoverished workers. When Norilsk was privatised in 1994, environmentalists hoped that its new private owners would pay more attention to the environment. But statistics from across Russia have shown just the opposite. With little working environmental regulations, most Russians are forced to accept terrible and dangerous working conditions and polluted air and water supplies. Here, in the final stages of nickel production, workers spend eight hours a day leaning over massive steaming vats of poisonous acid. Factory directors admit there are no respiratory protectors and no money to provide them in the future. With Russia's economy in a tailspin, workers at Norilsk are forced to think of their health last. Struggling just to get by, there is very little environmental awareness in places like Norilsk. Workers know they have little power and almost no choice. SOUNDBITE: (in Russian) "You know as far as the danger goes, we have a saying that goes like this - every farmer farms by his own choice - if you want work at all then you take what you can get. Every worker that comes here, they know what they are facing but they have no choice. If they want to work in Norilsk then they have to work in these factories." SUPER CAPTION: Sergey Zaitsev - has worked in acid baths for 10 years Very little grows in Norilsk's nearly year-round winter. And the earth is so polluted with heavy metals that residents are not allowed to gather even berries or hunt for mushrooms in the short summer months. Most residents in Norilsk are aware of their plight but are resigned to the futility of changing their environment. Although Russia has excellent environmental laws on the books, the legal system is practically non-functioning - so both private and governmental companies know that anything goes in terms of polluting. SOUNDBITE (in English) "It's getting worse because the enterprises have now come to private hands and it's very clear the control on those enterprises is extremely weak. And the number of people working in the Environment Ministry is less than six-thousand for the whole country and that means not only control but scientific research, levels and etcetera, etcetera." SUPER CAPTION: Ivan Blokin, Moscow Greenpeace In Russia's coal producing region of Kemerovo, the situation is similar. Decades of coal production without any environmental controls have left the region decimated.

Genetic Drift, Gene Flow, and Types of Natural Selection
 
04:04
Erika Tan explains the differences between genetic drift and gene flow, in addition to the three types of natural selection. *** If there are any pictures used in this video, they are NOT MINE and I will not take credit for them. *** TRANSCRIPT: Alright guys, so today we’re gonna go over events that influence allele frequencies in a population: that is to say, genetic drift and gene flow. At the end of this video, we’ll go over the types of natural selection. So, genetic drift is when chance events cause changes in allele frequencies. They’re unpredictable, and sometimes they can be detrimental if there ends up being a lot of a harmful allele in the population. There are two types of genetic drift: the founder effect and the bottleneck effect. The founder effect is when a small portion of individuals becomes isolated from the larger population. Let’s look at this island of birds I’ve drawn here. Perhaps a wind has caught the smallest birds, and they are not strong enough to fly against the wind. They’re blown onto another island, and… yikes! It looks like there have been a lot of green birds blown onto the island, and only one blue bird. Well, by chance, it seems that the blue allele is recessive, so over some generations, all of the birds on this new island will be green. When compared to the original population, the birds will seem very different. Over time, these two groups of birds may have adapted and diverged so much from each other that they become separate species. The bottleneck effect is another type of genetic drift, and it’s called that because it’s like shaking marbles out of a bottle. Since the neck of the bottle is so narrow, only a few individuals are able to survive from a random and sudden change in the environment. Perhaps a fire wipes out almost all of the birds on this island. By chance, the few survivors can be any individuals, regardless of their genotypes. The fire could burn down this portion of the island, leaving many green birds as survivors, or the fire could burn down this portion, leaving many blue birds – it’s all up to chance. Next up is gene flow – that’s basically immigration and emigration. Gene flow is the result of the movement of individuals. A good example given in the Campbell’s AP Biology textbook is that humans move freely around the world, and as mating occurs between different populations, you start to see different phenotypes appear. The contribution of one individual’s alleles to a population is therefore what gene flow is. Time for my favorite part of this whole video, the types of natural selection! You’re gonna love this too, since it’s so easy to understand. There are three types of natural selection: directional, disruptive, and stabilizing. Let’s say we have this graph set up, and along the bottom, we place different colors of mice. Over on this side we have the light-colored mice, and going to the right, the mice get darker and darker. Here’s your normal distribution curve: most of the mice have intermediate phenotypes, and very little have extreme phenotypes. Now, natural selection can act on this population in many different ways. This first one is called directional selection, in which the whole curve shifts to one direction. That way, the whole population of mice either becomes lighter as a whole or darker. Maybe the soil that the mice walk on is darker, so it’s easier for the darker mice to hide from predators. Or, maybe the soil is a very light color, so the distribution curve shifts to the direction of the left. The next one is called disruptive selection: the curve is disrupted, and only individuals with extreme phenotypes are favored. Maybe the soil has patches of very dark and very light dirt, and the intermediate-colored mice have no place to hide. Finally, stabilizing selection is when the population becomes more stable in terms of phenotypes. In other words, individuals with extreme phenotypes are selected against, and only intermediate-phenotype individuals are favored. As you can see, this results in a very narrow population variation. Perhaps the soil in this example is a brown color. Alright, thanks for watching, guys! Be sure to check out my other videos for more AP bio help, and I’ll see you in another video.

UNSW CENTRIFUGE FACILITY
 
03:56
UNSW Geotechnical Centrifuge Research Facility. This million dollar facility nicknamed the Environmental Time Machine, is a joint effort between the School of Mining Engineering and the School of Civil & Environmental Engineering. The centrifuge is helping researchers from Mining Engineering, ACSMP and across UNSW change the way engineers understand and access earth’s resources. Research in the facility includes testing barrier and caprock integrity for underground developments, measuring long term recharge rates for groundwater, and looking at geochemical reactions during slow underground flow. Centrifuge technology could also be useful to help design safer open cut and underground mining that reduces environmental impacts, and for testing the durability of tight membranes and materials.

Is Synthetic Motor Oil Better For Your Car?
 
07:23
Is synthetic motor oil better than conventional oil? Synthetic Motor Oil Myths - https://youtu.be/Se8-W7rK0H4 Thank you to Pennzoil for bringing me out to the 2016 Canadian GP and sponsoring this video! This video has been compensated by GarageMonkey and its advertiser. All opinions are mine alone. Subscribe for new videos every Wednesday! - https://goo.gl/VZstk7 The viscosity of an oil is its resistance to flow. A greater viscosity means more resistance to flow, or a thicker oil. A lower viscosity means a thinner oil. Before understanding the benefits of synthetic motor oils, like this Pennzoil Platinum derived from natural gas, we first need to understand the rating system used for motor oils. You’ll often hear 5W-30, or 0W-20 as ratings used in cars today. These are multi-grade viscosity oils, meaning their viscosity grade changes with temperature. The first number, followed by a W, is the cold rating (W stands for Winter), and this means the oil behaves like an SAE 5 grade motor oil (using 5W-30 as the example) while cold, but at operating temperature, at about 100 degrees C, it operates like an SAE 30 grade motor oil. Now 30 is higher than 5, so initially it may seem that the oil would get thicker at higher temperatures, which is obviously not the case. A straight SAE 30 grade oil will be thicker at lower temperatures, as will a 5 grade oil. Even though a 30 weight oil is thicker than a 5 weight oil, at 100C the 30 weight will be thinner than a cold 5 grade oil. Low viscosity at low temperatures is important, because this is where a significant amount of engine wear occurs, so it’s critical to maximize oil flow to protect the engine. At colder temperatures, thinner oils will flow better and thus offer better protection. For a conventional oil, for example while creating a 5W-30 oil, you’ll start with a base oil similar to an SAE grade 5 motor oil, and include additives to alter the viscosity rating. To improve low temperature flow, pour point depressants (PPDs) are added. To increase the viscosity at high temperatures, viscosity index improvers (VIIs) are added. VI improvers are polymers which expand in heat, making it more difficult for flow, thus increasing the viscosity. Synthetic oils, however, can have base oils which are already formulated as a multi-grade oil, meaning you don’t necessarily need additives, or as much additives, to alter the viscosity at different temperatures. The major benefit here is that additives tend to break down over time, so synthetic oils will maintain their original viscosity properties much better throughout the engine oil drain interval versus conventional oils. (Diagram illustrating viscosity vs temperature) If you were to plot two 5W-30 motor oils, one conventional and one synthetic, at the beginning of the oil change interval, they would have similar viscosity properties. At the end of the interval, however, the synthetic would act nearly identical to the original oil, while the conventional oil would be thicker at low temps, and thinner at high temps. Now does this mean that with synthetic motor oils you can extend your engine oil drain interval? No! It just means your engine is better protected throughout the engine oil drain interval. There are still additives (anti-wear, dispersants, anti-foam, detergents, rust inhibitors, corrosion inhibitors) which wear out over time, so you should always change at whatever interval your owners manual suggests.

A lot have disappeared since the Three Gorges dam was built. One of the main reasons is that those cold water fish can no longer swim up the stream from the place where they were born."

SOUNDBITE (Mandarin) Yu Wei, aqua-farm owner: "I hope one day I can find a male salamander so that she can have babies and we can start the reproduction of this species." 29. Various shots of Salamander STORYLINE: China's Three Gorges dam was built with the aim of controlling disastrous flooding on the Yangtze River and to help channel water for an ambitious project to supply water to the dry North. However, silt and debris in the river have begun to increase and drift offshore, although officials maintain they will be able to bring the pollution under control. One group directly affected by the anticipated change in the river ecology are fishermen, and many believe dozens of wild species will perish as their habitat changes. Liu Guangji has been fishing in the Three Gorges for more than 30 years, but says his profits are now dropping because his most profitable commodities such as bream, white eel and soft-shelled turtles are disappearing. Chinese sturgeon, which live in the upper streams of the Yangtze, are also under threat, and now the species is being bred in aqua-farms. Yu Wei, an aqua-farm owner, said she started to farm Chinese sturgeon two years ago when she realised the fish in the Yangtze River were disappearing. Yu's farm is at the foot of a mountain where a small branch of the Yangtze passes, where people travel hundreds of miles from cities along Yangtze river to enjoy the fish they can no longer find in their hometown. Yu is looking to farm other species of fish, and last year bought a giant salamander from a fisherman on the Yangtze river. Giant salamander are high on China's list of endangered species. Fish who live in the cold waters at the upper stream of the Yangtze and swim down to the warmer lower stream waters to produce their eggs are also affected. Once the eggs grow to small fish, they have to swim back upstream where they will turn into adults.

Silent environmental catastrophes - Part 1 Mining on the west coast of South Africa - full length
 
01:05:07
My experience in fighting against the corruption behind the commercialisation of nature conservation in South Africa taught me to look at the natural environment in a new way. No longer did I see all the wonderful things that the propaganda machine was telling us about. Instead I began to find environmental disasters with my own eyes all around me that were receiving no attention at all from government due to being too costly to address in one way or the other. The first environmental catastrophe I came across was the open cast mining on the west coast of South Africa. After spending about 6 months researching the subject the most important question I was unable to get an answer for from either government or private companies studying the effects of one medium sized mining house on the West Coast, was what is the cumulative effect of mining on the West Coast of South Africa and how much of this unique veld remains in its natural, undisturbed state?   Mining 'operations' have been going on on the West Coast of South Africa since the first diamond was discovered at Port Nolloth in 1925. The approximate length of the west coast coastline that mining houses are interested in is 450km which is made up of the extremely rare vegetation type called succulent Karoo that has plants and animals which occur nowhere else in the world. In 2003, one mining 'operation' by N.D.C. mining company Pty Ltd, a "medium" size mining company, sought to open cast mine an area of 5.7km of coast; which is approximately 1 ½ % of this unique biome. What have the large mining houses done to the rest of the coast in the preceding 80 years? This coastline and its resources, be they plant, animal, fossil or archaeological is finite. One environmental consequence of the open cast mining on the West coast of South Africa is desertification which is spreading from the West coast of South Africa like a deadly cancer. Cape Town which lies only a 100 kilometres south of the Succulent Karoo is already being affected by this. Incidentally the town of Vredendal which lies slightly inland from the west coast recently set the highest global temperature for October of 48.4°C.

Communities looking for coal mine answers
 
02:28
http://www.ctvvancouverisland.ca http://www.facebook.com/ctvvi CUMBERLAND - Despite having its history deeply rooted in the early days of coal mining, this village in the Comox Valley is adding its voice to others questioning whether a possible mine in the region is a good idea. Councillors for the village of Cumberland passed a motion calling for a more thorough environmental review of the Raven Underground Coal Project, which is being proposed for the Union Bay area. The village joins Courtenay, Comox and the Comox Valley Regional District in looking for an independent provincial baseline study as well as a federal joint review panel to look into the project. The communities are particularly interested in having aquifer mapping completed. The Wilderness Committee congratulated the municipalities on their unified approach to the proposed mine and said that environmental problems created by the project would be too great for the area. The committee's Vancouver Island Campaigner Torrance Coste said the mine would only have a lifespan of 16 years and would threaten several sustainable industries in the area.

Placer mining has over 250 year history literally starting on the United States of the East Coast in the late 1700s then moved to New Mexico, California, Nevada, Colorado, Alaska, among other western ore rich states. Reported in various official United States Bureau of Mines publications dating from the 1930s until today "placer gold can be found in virtually any area where gold occurs in hard rock (lode) deposits. The gold is released by weathering and stream or glacier action, carried by gravity and hydraulic action to some favorable point of deposition, and concentrated in the process. Usually the gold does not travel very far from the source, so knowledge of the location of the lode deposits is useful." Leia Michele Toovey in an exclusive article entitled YUKON: MODERN DAY GOLD RUSH in Gold Investing News reports that just in the Yukon region of Alaska, "Small placer gold mines operating in the region have a combined annual production of approximately 100,000 troy ounces. The total recorded gold production from 1885 to date is about 12.5 million ounces, a value of roughly US $15 billion at today's prices." A working placer mine involves everyone from children to grandparents. As witnessed by the writer during a recent on-site television production tour in Ridgecrest, California numerous Mojave Desert placer miners lead the world in safe and efficient gold recovery, while making significant contributions to the state and national economy. The United States Bureau of Land Management and the California Geological Survey have established regulations and legislation to ensure environmental stewardship, land reclamation, mining sites restoration, and protection of native flora and fauna. www.emerald-planet.orttp://tinyurl.com/6qphtxr (Facebook) http://twitter.com/#!/emeraldplanet1 (Twitter) http://tinyurl.com/7a2ru7f (Linkedin)

The Circulation of the Antarctic Margins in a Changing Climate
 
53:18
“The circulation of the Antarctic margins in a changing climate,” is presented by Dr. Andy Thompson, a physical oceanographer and Professor of Environmental Science and Engineering at Caltech. Ocean circulation at the Antarctic margins is dominated by a system of circumpolar frontal currents that occupy the continental shelf and slope. This Antarctic Slope Frontal (ASF) system has a significant impact on global climate through its control over the transport of warm water towards Antarctica's floating ice shelves and over the properties of bottom waters exported from the Antarctic shelf. In the past two decades, appreciation of the spatial and temporal variability of the ASF and its impact on heat and tracer transport has grown through a combination of novel in situ observational techniques, remote sensing and high-resolution numerical modeling. This talk will highlight how these different approaches have improved our dynamical understanding of the ASF and its role in the global circulation and climate system. This is a recording of a presentation organized by NASA Jet Propulsion Laboratory's Center for Climate Sciences as part of its Distinguished Climate Lectures on February 7, 2018 in Pasadena, Calif. https://climatesciences.jpl.nasa.gov

2017 Ralph B. Peck Lecture: A New Paradigm for Slope Stability Analysis
 
43:01
2017 Ralph B. Peck Medal Lecture: A New Paradigm for Slope Stability Analysis under Variably Saturated Conditions Ning Lu Ph.D., F.EMI, F.ASCE, Colorado School of Mines This lecture will highlight two major advancements in slope stability analysis that stemmed from several multi-year field hydro-mechanical monitoring. The first significant breakthrough is the capability to handle the transient field of effective stress in variably saturated slopes under rainfall conditions. Using effective stress analysis preserves the rigor, simplicity, and practicality of the classical slope stability methodologies (e.g., limit equilibrium). The second is to quantify the field of local factor of safety (FS), which radically departs from the classical one-FS-for-one-slope paradigm and allows identification of failure initiation and progression zones in slopes. The new hydro-mechanical framework for slope stability design and analysis only requires three parameters in addition to the classical shear strength and seepage parameters. These parameters are used to uniquely define slope materials’ constitutive relations of the soil water characteristic curve, hydraulic conductivity function, and suction stress characteristic curve. Several field cases are used to illustrate the validity, accuracy and simplicity of the new hydro-mechanical framework for slope stability analysis. The Ralph B. Peck Medal Lecture is delivered annually by a geotechnical engineer selected for outstanding contributions to the profession through the analysis and publication of case histories. BIO: Dr. Lu was selected by the Geo-Institute Board of Governors to receive the 2017 Ralph B. Peck Award “For his multi-year case study monitoring the subsurface hydrological and mechanical conditions leading to landslide occurrence on the coastal bluffs between Seattle and Everett, WA, and using the data collected to develop a new hydro-mechanical framework for slope-stability analysis.” In selecting him for this award, the committee particularly noted his body of research on rainfall-induced land sliding.

Ron Lewko, Environmental Research, Syncrude
 
01:59
I'm Ron Lewko and I look after environmental research at Syncrude and my job is to reclaim the land. So this whole area was a mining operation about 15 years ago. It was a 30 meter deep hole right from the top of oil sand right down to the limestone. There was really nothing here. About 12 years ago we started replacing the over-burdened back into this area, contoured the land, put reclamation soil on it. After that...we start planting the seedlings in about year two. We have a standard reclamation prescription on planting of trees and as you can see they're everything from white spruce to poplar. I think we've planted over five million trees and shrubs. Once reclamation started, nature took over and the wetland took off by itself. These bulrushes came in naturally. The willow trees around the lake came in naturally. We've got wildlife in here. Some of the wetland's wildlife that we've seen is ducks, the sandhill crane but also the macrophytes, the little stuff that sustain it. All the bugs and bacteria that are at the bottom of the food chain to sustain some of the bigger wildlife here. I'm involved in some of the aboriginal consultation and that's where we get some of the ideas that rat root is very important... they've been telling us for quite a while in the past that LFH was very important to them...meaning that we'd take the top of the forest floor and put that on the final lift of our reclamation and in fact what they said was true, it just took off and we've seen more success in 6 months than in some of our reclamation areas have seen in 2 years. Even though it's fifteen years old things are taking off. I've got wildlife in here, the bulrushes are going crazy. It's just a nice place to be.
2017 H. Bolton Seed Medal Lecture: Numerical Analysis of Stability and Risk in Highly Variable Soils
 
58:45
2017 H. Bolton Seed Medal Lecture: Numerical Analysis of Stability and Risk in Highly Variable Soils D. Vaughan Griffiths Ph.D., P.E., D.GE, F.ASCE, Colorado School of Mines There has been a rapid growth of interest in risk assessment, and the use of probabilistic methods in geotechnical engineering. This is a logical development, since soils and rocks are among the most variable of all engineering materials, and geotechnical engineers must often make do with materials they are dealt with at any particular site. Analysis of a typical stability problem may lead to a “probability of failure”, as opposed to the more traditional “factor of safety”, representing a fundamental shift in the way engineers need to think about the suitability of their designs. The lecture will include results of stability analyses of variable soils by the finite element method, and include a discussion of the factor of safety and its relationship to the probability of failure. Some methods of probabilistic analysis with varying levels of complexity will be described. The H. Bolton Seed Medal Lecture is given annually by the recipient of the H. Bolton Seed Medal for outstanding contributions to teaching, research or practice in geotechnical engineering. BIO: Dr. Griffiths was selected by the Geo-Institute Board of Governors to receive the 2017 H. Bolton Seed Medal “For his innovative software developments, publications, textbooks and professional short courses on finite elements and probabilistic methods. His highly-cited work on finite element stability analysis has transformed the way engineers perform slope stability analysis in practice.” In selecting him for this award, the committee particularly noted his reputation as a pioneer in numerical modeling.

This teleconference was recorded on September 29, 2011. You will need to download the presentation slides (PDF) at https://www.akaction.org/the-role-of-health-impact-assessments-hias-in-decisions-that-affect-communities-a-case-study-of-proposed-coal-mining-in-the-matanuska-valley/ Speakers: Shawna Larson, Alaska Program Co-Director, Pacific Environment Liz Snyder, Assistant Professor of Public Health in the Department of Health Sciences at the University of Alaska Anchorage Description: Environmental impact assessments, required under the National Environmental Policy Act (NEPA) typically focus on impacts to plants and animals, with less thorough assessment of the human health impacts of a proposed development project. A health impact assessment (HIA) is a process that uses scientific evaluation, professional expertise and stakeholder input to study health effects. The National Academy of Sciences recently endorsed the inclusion of HIAs as important in environmental review. Health impact assessments have been used internationally and are gaining traction in some states, including Alaska, as a voluntary process for assessing health effects among potentially affected communities. Alaska is seen by some as a leader in developing HIAs. In 2007, a health assessment was done under NEPA for the first time to assess the health implications of oil and gas development on the North Slope. The State of Alaska is working on a "rapid assessment" HIA for the Wishbone Hill Coal project.
Wild SideTV-The Obey River.mpg

Ever since the formation of the Sewanee Mining Company in the 1850s, coal has helped put food on the table for many people living on the Cumberland Plateau. It was an industry built mostly by the sweat of good people trying to earn a living the only way they knew how. But what they didn't know was that the very thing that helped them survive was also killing the life they knew. Today the Plateau is still feeling the effects of those old coal mines. Wild Side Guide Ken Tucker takes us to the Obey River, where clear waters often hide a silent killer...acid mine drainage. At one time the Obey was considered dead...barren of almost all forms of aquatic life. But now, thanks to the hard work of the Tennessee Department of Environment and Conservation and the TWRA, the river is beginning to recover. It will take many more years and a lot more work...but even then, the Obey might never be the same. To learn more about coal mining in Tennessee on the Cumberland Plateau, try Jason Duke's book "Tennessee Coal Mining, Railroading, & Logging in Cumberland, Fentress, Overton and Putnam Counties" available through this website http://www.tncoal.com/. Special thanks to Jason, Kendall Morgan, and David Johnson for letting us use their coal mining pictures in this story. David has amassed a large collection of old mining pictures that can be viewed on his website at www.miningartifacts.org. For more stories like this, visit our website at www.wildsideTV.com
